My 7100 started acting strange with D-Rats (039 version). Over the USB connection for data when I transmit chat the radio repeatedly keys up. First transmission after changing a connection or something is usually normal...keys up, sends, shuts down. Subsequent chat keys up like 5 times and appears to keep sending the same thing. It did not do this awhile ago. The 7100 is not my normal D-Rats radio ( I use an 880H with the orange cable) so hard to say when this began....new version of D-Rats, some kind of windows update...not sure. My feeling (guess) is there is some kind of buffer trying to send again and again. I plugged an orange cable into the 7100 and it works exactly like my other radios....keys up, sends data, shuts down. A member of our Thursday D-Rats group is having the exact same issue with an Icom 9700 over USB. Otherwise I'd think it was just my computer. Any ideas? Anyone else see this? ONLY on the USB conection, and ONLY on D-Rats DV data...JS8Call, FLDigi....all that works perfect over USB.?
